Just moved into a place with a pool, and after blindly listening to the pool store people with no decent results, I've decided to take it into my own hands.
Just got my TF-100 in the mail so I was excited to give it a whirl. I have a couple of questions though:
1) For the T/A test. Am I adding drips 'till it turns RED red, or as soon as it flips to a pinkish? I'm assuming as soon as it flips.
2) For the CH test. It doesn't look like the reagent fully mixed with the water. Looked like little flakes in there. They did turn blue, however. It just seemed like a very high number compared to my last two pool store results and the hardener that I added. (started at 85, added 8lbs of hardener) Pool store measured 225, I measured ~270.
3) For the CYA test, how hard am I looking for that black dot? obscured or absolutely cannot see it? I can see it if I concentrate hard enough, but i don't know if I'm making too much of an effort. I was most concerned about this number. Pool store said I was at 0 on my first test, so I added 4lbs of solid acid. Next test from them had me at 100, which I thought was from my chlorinator. My result was around 20, depending on my answer to the above question. I believe none of them if I actually did start at zero.
By the way, I emptied out the chlorinator. It had completely eaten one puck and the other 6 were thinning out, but still there. I'm not going to be using it, except for when I'm out of town. It takes for-ev-er to drain water from my pool, so I don't want those CYA levels up.
Anywho, I'm going to use this thread to get myself from the mess I have now to a sparkling pool.
My main issue right now appears to be black algae. It's all over the shallow end an there's spots in the deep end. Other than that (ha), I just have to keep the sand from accumulating.
On to my first results:
I'm going to go to mustard shock level asap and keep it there 'till I grow arms of steel scrubbing all of the black algae.
